Several elements can affect the legibility of your emails on mobile devices:
Font Size: Smaller fonts can be difficult to read on smaller screens. A minimum font size of 14px is recommended. Line Spacing: Adequate spacing between lines and paragraphs makes the text easier to read. Aim for a line height of at least 1.5 times the font size. Responsive Design: Ensuring your email layout adjusts to different screen sizes is crucial. Use media queries in your CSS to make your emails responsive. Images and Graphics: Optimize images for mobile devices to ensure they load quickly and display correctly. Use alt text for images that may not load. Call-to-Action (CTA) Buttons: Make sure your CTAs are large enough to tap easily and are clearly visible.
